I have a choice of either getting an ASUS GTX 670 DC2T or a Sapphire 7970 Ghz Vapor-X. I plan on SLI/Crossfire-ing this card in the future. The Sapphire 7970 Ghz Vapor-X Edition is a 2.5-slot card, will it Crossfire work normally on an Asrock z77 Extreme4 mobo? Will the cooling be greatly decreased due the the decrease in the gap between both cards on the mobo? I will be using an NZXT Phantom 410 with 2 top exhaust, 1 rear exhaust and 2 front intake fans. Will the 2gb memory on the 670 hinder its ability in the future?
dont even bother with a ftw 670. its just a 670 on a 680 pcb and cooler. the asus is way better in terms of overclocking and msi would get you the highest clocks since you can over volt (that feature was taken out on newer batches of cards)
id get the 7970 ghz edition though since it performs the best
But mostly depends on games you are playing and maybe the resolution.
There is the GTX 670 FTW that performs nearly as the stock Gtx 680 and it can clock higher easily.
Alright, then I guess for now I'm going to get the Sapphire 7970 Ghz Vapor X Edition, and then overclock it like mad. How will the Sapphire 7970 Ghz Vapor X fit in my mobo with my case cooling? Will the shortage of distance between the cards affect the cooling by A LOT?
